The 6th is this long narrow district that stretches nearly the entire length of the state. That appears contrived to me.
I would have a computer find contiguous population clusters of the amount of people required to be in each congressional district with the shortest distance possible from one side of a district to the other.. There are clustering analyses available.
River centric is both a blessing and a curse. The Ohio River is our main highway; it's possible to travel by boat and visit most of the district. Worst part of sixth district being the long ground travel distances without the benefit of a divided highway system. For example, no where within Lawrence County does a posted highway speed exceed 55 mph.
Contrived? In reality, a district of shared concerns could be stretched west among river counties to Cincinnati. The oddest fit being the district's northerly sector of Youngstown metro juxtaposed against the remainder of the region; population within some of Youngstown precincts exceeds the total population of Lawrence County. Aside from historic footnotes of long past metallurgic ages, this Youngstown region shares little in common with Ironton.
